[0031] Currently, the brightness and color of elevator car lights vary depending on the environment. The relevant parameters are stored in the drive board. However, when there is a power outage, the drive board is no longer in operation, so the internal parameters will be lost. After the power is restored, the parameters in the drive board need to be manually adjusted, which greatly increases the labor cost and reduces efficiency.

[0032] Based on this, this application proposes a lighting control circuit, system, car, and elevator for an elevator car, which aims to ensure that the drive board can still be in working condition during a power outage by setting up an emergency power supply, so that the lighting parameters can be maintained.

[0033] The following reference Figure 1 and Figure 3 This application describes a lighting control circuit for an elevator car according to an embodiment of the present application.

[0034] It can be understood that the light control circuit of the elevator car in the embodiment of the application comprises a lamp set, a driving board and an emergency power supply, the lamp set comprises a first light emitting element, a second light emitting element, a third light emitting element and a fourth light emitting element; a first output end of the driving board is connected with one end of the first light emitting element and the third light emitting element through a first switch, the other end of the first light emitting element is connected with the second output end of the driving board through the second light emitting element, the other end of the third light emitting element is connected with the third output end of the driving board through the fourth light emitting element, the first switch is used for controlling conduction or cut-off between the driving board and the first light emitting element and the third light emitting element, the driving board is used for controlling brightness of the first light emitting element, the second light emitting element, the third light emitting element and the fourth light emitting element; the emergency power supply is connected with an input end of the driving board, and the emergency power supply is used for providing current for the driving board when power is off.

[0035] The beneficial effects of the elevator power supply circuit in the embodiment of the application can be shown as follows: by arranging the first light emitting element, the second light emitting element, the third light emitting element and the fourth light emitting element, the light source of the car is ensured to be sufficient, and the range of the brightness that can be adjusted is large; by arranging the driving board, the brightness of the lamp set can be adjusted by adjusting the parameters in the driving board, so that the adaptability is improved, and the use experience of the passengers is optimized; by arranging the emergency power supply, the power supply of the driving board is separated from the power supply of the elevator, so that the emergency power supply can still provide current for the driving board when the elevator is powered off, the light parameters in the driving board are saved, and manual adjustment is not needed after the power supply of the elevator is restored, so that the efficiency is improved and the labor cost is reduced; by introducing the light control circuit of the elevator car, the part that saves the light parameters after power off can still work, so that the light parameters do not need to be adjusted after the power supply is restored, and the labor cost is reduced.

[0036] For example, in some embodiments, reference is made to Figure 1 and Figure 3In the embodiment, the second switch is further included, the lamp group further includes a fifth light emitting element, a sixth light emitting element, a seventh light emitting element and an eighth light emitting element, wherein D1 is the first light emitting element, D2 is the second light emitting element, D3 is the third light emitting element, D4 is the fourth light emitting element, D5 is the fifth light emitting element, D6 is the sixth light emitting element, D7 is the seventh light emitting element, D8 is the eighth light emitting element, K1 is the first switch, K2 is the second switch, both input ends of the driving board are connected with the power grid, the fourth output end of the driving board is connected with one end of the fifth switch element and one end of the seventh switch element through the second switch, the other end of the fifth switch element is connected with the fifth output end of the driving board through the sixth switch element, and the other end of the seventh switch element is connected with the sixth output end of the driving board through the eighth switch element, the driving board stores the parameters such as brightness and color light of the first light emitting element, the second light emitting element, the third light emitting element, the fourth light emitting element, the fifth light emitting element, the sixth light emitting element, the seventh light emitting element and the eighth light emitting element, the parameters in the driving board can be adjusted artificially, and then the brightness, color light and the like of the first light emitting element, the second light emitting element, the third light emitting element, the fourth light emitting element, the fifth light emitting element, the sixth light emitting element, the seventh light emitting element and the eighth light emitting element are changed, so as to increase the adaptive range of the light control circuit of the elevator car. The first switch and the second switch are consistent in state, that is, they are simultaneously closed or opened, so as to ensure the consistency of the light in the car and avoid the bad experience of the passengers caused by the uneven light in the car; the emergency power supply is connected with the driving board through the power grid, and the setting of the emergency power supply facilitates the power supply to the driving board through the power grid, so as to separate the power supply of the driving board and the power supply of the elevator, and then ensure that the driving board can still work when the elevator is powered off, avoid the loss of internal parameters, and reduce the labor cost.

[0037] It can be understood that the light control circuit of the elevator car further includes a relay, an input end of the relay is used for connecting the power grid, and an output end of the relay is connected with the first switch.

[0038] For example, in some embodiments, reference is made to Figure 2 In the embodiment, the output end of the relay is further connected with the second switch, and the first switch and the second switch are controlled by the same relay KM6, so as to ensure the synchronization of the first switch and the second switch and make their states consistent.

[0039] It can be understood that the first switch is a normally open switch.

[0040] For example, in some embodiments, in the present embodiment, the second switch and the first switch are both normally open switches, so that in general, the driving boards are not conductive, thereby causing the first light emitting element, the second light emitting element, the third light emitting element, the fourth light emitting element, the fifth light emitting element, the sixth light emitting element, the seventh light emitting element and the eighth light emitting element are not working, until the first switch and the second switch are closed when a passenger enters the car, thereby the first light emitting element, the second light emitting element, the third light emitting element, the fourth light emitting element, the fifth light emitting element, the sixth light emitting element, the seventh light emitting element and the eighth light emitting element are in working condition, there is light in the car, thereby realizing that the light group works only when there is a passenger in the car, reducing power consumption and reducing the operating cost of the car.

[0041] It can be understood that the control circuit of the elevator car light also includes a transformer, and the input end of the relay is connected with the power grid through the transformer.

[0042] For example, in some embodiments, referring to Figure 2 In the present embodiment, the input end of the transformer is connected with the power grid, and the output end of the transformer is connected with the relay, thereby the transformer converts the voltage input by the power grid into a suitable voltage level and outputs to the relay, avoiding damage to the relay due to voltage mismatch.

[0044] For example, in some embodiments, referring to Figure 2 In the present embodiment, the power supply is WY2, and the transformer is connected with the relay through the power supply, so that the power supply can make the input signal input by the transformer more stable.

[0045] It should be noted that referring to Figure 2 The positive input end and the negative input end of the power supply can be connected with multiple relays, and the multiple relays are connected in parallel and control the first switch and the second switch of the corresponding driving board respectively, so as to realize centralized management and simplify the circuit.

[0046] It can be understood that the power supply is a switching power supply.

[0047] For example, in some embodiments, referring to Figure 1 In the present embodiment, the power supply is a switching power supply, so that the switching power supply can reduce the 220-volt alternating current input by the power grid to 24-volt direct current, thereby realizing the conversion of current type and the change of current size, and avoiding damage to the relay due to current mismatch.

[0048] It can be understood that the first light emitting element, the second light emitting element, the third light emitting element and the fourth light emitting element are all light emitting diodes.

[0049] For example, in some embodiments, with reference to Figure 1 In this embodiment, the first light emitting element, the second light emitting element, the third light emitting element and the fourth light emitting element are all light emitting diodes, so as to reduce energy consumption, and the light emitting diodes are low in cost, thereby reducing the production cost.

[0050] According to the system of the second aspect of the application, the light control circuit of the elevator car comprises the light control circuit of the elevator car of the first aspect of the application.

[0051] According to the light control circuit of the elevator car of the application, the first light emitting element, the second light emitting element, the third light emitting element and the fourth light emitting element are arranged, so as to ensure sufficient light source of the car, and the range of the adjustable brightness is large. The driving board is arranged, so that the brightness of the lamp group can be adjusted by adjusting the parameters in the driving board, thereby improving the adaptability, and the use experience of the passengers is optimized. The emergency power supply is arranged, the power supply of the driving board is separated from the power supply of the elevator, and the current of the emergency power supply can be provided for the driving board when the elevator is powered off, so that the light parameters in the driving board can be saved, and manual adjustment is not needed after the power supply of the elevator is restored, thereby improving the efficiency and reducing the labor cost. The light control circuit of the elevator car of the application is introduced, so that the part of the light parameters saved after power failure can continue to work, and the light parameters do not need to be adjusted after the power supply is restored, thereby reducing the labor cost.

[0052] Since the system comprises the light control circuit of the elevator car of the first aspect of the application, the corresponding contents of the light control circuit of the elevator car in the first aspect of the application can be applied to the system of the second aspect, and have the same implementation principles and technical effects. To avoid redundant description, the detailed description is not given here.

[0053] According to the car of the third aspect of the application, the system of the second aspect of the application is included.

[0054] According to the elevator of the fourth aspect of the application, the car of the third aspect of the application is included.
